Dow CAT 10000PA CMC PEO HPMC Thickener

Features Of Dow CAT 10000PA CMC PEO HPMC Thickener

1. Multi-polymer synergistic formulation combining carboxymethyl cellulose (CMC), polyethylene oxide (PEO), and hydroxypropyl methylcellulose (HPMC) for balanced rheology and enhanced suspension stability.

2. High-shear reversible thickening behavior ideal for pumpable, sprayable, and high-solids formulations without gelation or stringiness.

3. Excellent compatibility with electrolytes, surfactants, and common industrial additives across a broad pH range (3–11).

4. Low-foaming profile suitable for high-agitation processing and automated dispensing systems.

5. Consistent batch-to-batch performance supported by Dow’s stringent quality control and traceable manufacturing standards.

Typical Applications Of Dow CAT 10000PA CMC PEO HPMC Thickener

1. Architectural coatings: interior/exterior flat and low-sheen paints requiring sag resistance and spatter control.

2. Industrial maintenance coatings: primers and topcoats for metal and concrete substrates requiring extended wet-edge time.

3. Agrochemical suspensions: water-dispersible granules (WDG) and suspension concentrates (SC) demanding long-term particle stabilization.

4. Cleaning formulations: heavy-duty liquid detergents and disinfectants requiring viscosity build and active ingredient homogenization.

5. Construction mortars and tile adhesives: cement-based and polymer-modified systems requiring open time and anti-sag performance.

Dow CAT 10000PA CMC PEO HPMC Thickener – Frequently Asked Questions (FAQ)

Q1: What is the primary functional role of Dow CAT 10000PA in formulations?

A: Dow CAT 10000PA is a multi-polymer thickening system designed to provide synergistic rheology control—enhancing viscosity, improving suspension stability, and delivering non-drip or shear-thinning behavior depending on the application. Its blended composition leverages complementary mechanisms from CMC, PEO, and HPMC for balanced performance across pH and ionic strength ranges.

Q2: Is Dow CAT 10000PA suitable for use in water-based coatings and architectural paints?

A: Yes—it is commonly used in waterborne architectural coatings, including interior and exterior paints, where it contributes to brushability, spatter resistance, and sag resistance. It maintains good compatibility with common latex binders and pigment dispersions, and its performance remains stable under typical storage and application conditions.

Q3: How should Dow CAT 10000PA be incorporated into a formulation to ensure optimal dispersion and activation?

A: For best results, pre-disperse the product in cold water using high-shear mixing before gradual addition to the main batch. Avoid direct addition to hot or highly viscous phases. Hydration time may vary depending on formulation pH and presence of electrolytes; allow sufficient residence time (typically several minutes) for full polymer unfolding and viscosity development.

Q4: Does Dow CAT 10000PA exhibit sensitivity to pH or salt content?

A: While the blend offers broader tolerance than single-polymer thickeners, performance can be influenced by extreme pH (<4 or >11) or high concentrations of multivalent ions. Formulators are advised to evaluate rheological response under representative end-use conditions, particularly when formulating with hard water or acidic/buffered systems.

Q5: Can Dow CAT 10000PA be used in personal care applications such as shampoos or lotions?

A: Yes—its components are widely accepted in cosmetic-grade formulations for viscosity building and texture enhancement. However, final suitability depends on compliance with regional regulatory requirements and compatibility testing with actives, preservatives, and surfactants present in the specific formulation.
